What Causes Fall Allergies, and How Can My HVAC Help?

September 28, 2021

The leading contender for what causes fall allergies in our region is ragweed. It can be a prolific contributor to fall misery. Even if you don't have any growing nearby, with the help of a good wind, the pollen can travel from miles away.

Besides this common weed, other sources of pollen include the trees, grasses, and shrubs that have inconspicuous flowers contribute to what causes fall allergies. These plants rely on the wind for pollination, rather than those with showy flowers whose primary pollinators are birds and bees.

Fortunately, you can use your heating and cooling system to reduce the amount of pollen in the air to mitigate the misery. Most of the allergies in this region are airborne pollen, which can be reduced and trapped by:

  • Installing a new air filter that is designed to trap the offending pollen. Be sure it’s rated at “better” or “best” for the most effective pollen entrapment.
    You can also go by its MERV (minimum efficiency reporting value), which should be higher than 5. Air filters have MERV ratings that range from 1 to 16 for home HVAC systems, and the higher the rating, the smaller the particle the filter traps. If what causes fall allergies for you has extremely small pollen, consider installing a filter with a MERV of 8 or higher.
  • Having your HVAC contractor tune up your equipment. When our HVAC technicians maintain your equipment, they thoroughly clean it. They will remove all the dust that accumulates inside the equipment and inspect the ductwork.
    If dust and debris has accumulated in the ductwork, they may recommend that you schedule a thorough ductwork cleaning, especially if they spot any mold growth inside the ducts or air handler.
  • Considering a whole-house air cleaner. These systems attach to your air handler and work continuously to keep the indoor particulate level low. You’ll benefit year-round from air that's free from pollen, dander, and dust, all of which may irritate your allergy symptoms year-round.
